High Current Sensor User Manual
Order Code: HCS-BTA
The High Current Sensor is used to measure current in the range of –10 to +10 A. The sensor uses a Hall Effect chip, so that it does not add a resistive element to your circuit. A replaceable fuse protects the equipment and circuit. Use the sensor in experiments that involve currents larger than 1 A, such as solar panels, hand generators, etc.
Note: Vernier products are designed for educational use. Our products are not designed nor are they recommended for any industrial, medical, or commercial process such as life support, patient diagnosis, control of a manufacturing process, or industrial testing of any kind.

Getting Started
- Connect the sensor to the interface (LabQuest Mini, LabQuest 3, etc.)
- Start the appropriate data-collection software (Graphical Analysis, LabQuest App, Logger Pro) if not already running and choose New from the File menu. The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.
If you are collecting data using a Chromebook™, mobile device such as iPad® or Android™ tablet, or a Vernier wireless sensor or interface, please see the following link for up-to-date connection information:

Calibrating the Sensor
You should not have to perform a new calibration when using the High Current Sensor in the classroom. We have set the sensor to match our stored calibration before shipping it. You can simply use the appropriate calibration file that is stored in your data-collection program from Vernier. To improve the accuracy, you have a couple of options. (1) Connect the sensor’s terminals with an alligator wire and simply use the data-collection software to zero the sensor. (2) Use the software to perform a two point calibration. This method is especially useful if you want to accurately measure current over a narrow range.
Safety
Students need to use caution when performing experiments with voltages and currents produced by any voltage other than low voltage, e.g., voltages under 5 V. This sensor is designed for large current. Students need to exercise extra caution when dealing with high voltage and current which can cause serious injury. They should only subject the sensor and circuitry to the currents and voltages designed for the devices. Students should keep all equipment away from water and other liquids.

Care and Maintenance
Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so can irreparably damage the wires and is not covered under warranty.
How the Sensor Works
The High Current Sensor contains a Hall Effect chip that senses a magnetic field produced by the electric current. The magnetic field through a short section of wire is monitored. The strength of the field is directly related to the current. With this method no resistive element is placed in the circuit. A metal film around the sensor helps to shield the sensor from magnetic fields. The sensor reading can still be affected by external magnetic fields. It is best to keep strong magnets or sources of strong magnetic fields away from the sensor during data collection.
Troubleshooting
For troubleshooting and FAQs, see www.vernier.com/til/2324
Replacing the Fuse
The sensor contains a replaceable 10 A fuse. If the sensor stops measuring current, you may need to replace a blown fuse. Turn the sensor over and remove the four screws on the back. The fuse can be seen from the top. Use a small screw-driver to remove the fuse. Insert a replacement. One replacement has been included with the sensor. Additional replacements in packs of five can be purchased from Vernier (order code FUSE-HCS).
